From Saint Jacques sent. (7), up to Fiery, continue x Plan Verraz-Dessous, when you begin to climb the path cuts the driveway, at the last hairpin bend, turn left and you reach the bridge over the Verrez torrent x give a glimpse of the lake Blue. Continue towards the upper Vallone del Verraz 2,300 m, where the climb to the Mezzalama Hut 3,020 m begins. A large part extends along the ridge that divides the two branches of the Veraz stream. First stop at the Mezzalama Refuge!
